HMS Nelson (28) was one of two Nelson-class battleships built for the Royal Navy between the two World Wars. She was named in honour of Horatio Nelson, 1st Viscount Nelson the victor at the Battle of Trafalgar.
Commissioned in 1927, Nelson served extensively in the Atlantic, Mediterranean and Indian oceans during the Second World War. She was decommissioned soon after the end of the war and scrapped in 1949. She was nicknamed "Nels-ol" from the resemblance in her outline to RN oilers, whose names ended in "-ol".
On her head is her peculiar headgear which features the various details of the top of her main tower.
